- Planform: both are listed as elliptical.
- JFX 2 has 9 cells; Petra has 7 cells.
- Both are cross-braced.
- JFX 2 is listed in 69–119 sq ft; Petra in 55–89 sq ft.
- The listed size ranges overlap between 69 and 89 sq ft.
- JYRO's recommended wing-loading range: JFX 2 1.6–2.2 lb/sq ft, Petra 2.5–3.0+ lb/sq ft. A range is a manufacturer envelope, not a target.
Structural facts only (manufacturer, planform, cells, bracing, sizes, chart system). How each wing flies is described below in the manufacturer's own words; how it flies for you is a question for a canopy coach.

| Characteristics (manufacturer keywords) | Predictable, soft crossbraced openings · Light, instinctive harness inputs · Dive longer than the original JFX but not as long as Leia · Slow, predictable, adjustable recovery arc · Immense bottom-end flare Source: JYRO — JFX 2 product page (page modified 2026-09-02) ↗ | Firm but not hard openings · Highly sensitive toggles and harness · Very long, steep dive · Long recovery requiring pilot input for level flight · High-speed stalls possible with abrupt inputs Source: JYRO — Petra product page (page modified 2026-09-15) ↗ |
| Opening | Predictable, soft crossbraced openings — 'the ace card of this canopy' (JYRO). | Firm but not hard; brisk when terminal (JYRO). |
| Recovery arc | Slow, predictable, easily adjustable recovery arc (JYRO). | Long recovery — requires pilot input for level flight (JYRO). |
| Glide | not published | High maximal glide ratio (JYRO). |
| Speed / dive | Dive longer than the original JFX, not as long as Leia (JYRO) — no airspeed figures published. | Very long, steep dive; 'the most high performance wing you can buy' (JYRO) — no airspeed figures published. |
| Flare | Immense bottom-end flare; stalls later (JYRO). | Very powerful and responsive (JYRO). |
| Front risers | Effective; slow the canopy a little before the turn to reduce pressure (JYRO). | Very light (JYRO). |
| Rear risers | Light, instinctive, trustworthy (JYRO). | Range, range and more range; very responsive (JYRO). |
| Harness response | Light, instinctive, very responsive — can be flown largely on harness (JYRO). | Highly sensitive (JYRO). |
| Toggle response | Powerful and responsive at the bottom end (JYRO). | Highly sensitive; high-speed stalls possible with abrupt inputs (JYRO). |
| Loading system | Recommended wing-loading range 1.6–2.2 lb/ft² plus a chart with jump-number bands (below). | Recommended wing-loading range 2.5–3.0+ lb/ft² plus a chart with jump-number bands (below). |
| Manufacturer-stated experience requirements | none stated |

Flight wording is quoted or closely paraphrased from each manufacturer's own documents; where a manufacturer publishes nothing for a row it says "not published". No airspeed figures are published by either manufacturer.
Your wing loading on each size
Enter an exit weight to see exit weight ÷ size for every listed size of both canopies and where each number sits on the manufacturer's own chart.
Wing loading = exit weight (lb) ÷ size (ft²). PD's chart lists the MAXIMUM exit weight per skill category — the category shown is the lowest one whose maximum covers your weight, by PD's own rule. JYRO's range is a manufacturer envelope, not a target. The two systems are never translated into each other.
